摘要
目的 探讨胰腺实性假乳头状瘤（SPT）的诊治方法.方法 本组4例均经病理证实.1例行MR检查,2例行增强CT检查,1例妊娠3个月常规检查时发现胰腺肿物.肿物分别位于胰腺勾突（1例）、胰腺颈部（1例）及胰腺体尾部（2例）.行胰十二指肠切除术、肿物局部切除术各1例,行胰腺体尾部切除术2例.肿物最大直径5cm～16 cm,平均10.3cm.4例血常规及生化无特殊异常,血清肿瘤标志物AFP、CA19-9、CA125、CEA均正常.术后标本均行病理及免疫组化检查.结果 4例病理诊断均为SPT.镜下见瘤组织呈实性巢状或围绕血管形成假乳头状结构.Vimentin、α-ACT、α-AAT表达阳性,CgA阴性.4例均痊愈出院,随访6个月未见复发.结论 SPT为低度恶性肿瘤,CT和MR是常用的检查方法,彻底手术切除是其治疗的有效手段,预后良好.
Objective To discuss the management of solid-pseudopapillary tumor of the pancreas. Methods Four patients of solid-pseudopapillary tumor of the pancreas （SPT） were diagnosed by pathology. One patient was underwent magnetic resonance and two enhanced computer tomography scan. The mass was located in tuberculum （1 case）, neck （1 case）, and body-tail （2 cases） of pancreases respectively. Four cases were underwent duodenopancreatectomy, local resection of mass, resection of body-tail of pancreases respectively. The maximal diameter of tumor ranged from 5 cm to 16cm, averaged 10.3cm. The blood regular test and biochemistry were normal, and the tumor markers including AFP,CA19-9,CA125,CEA also were normal. The specimens were examined by pathology and immunohistochemistry. Results Four cases all were diagnosed solid-pseudopapillary tumor of the pancreas by pathology. At histologic analysis, the tumor was composed of uniform polygonal cells with moderate to abundant amphophilic cytoplasm and arranged in solid nests with areas of degeneration characterized by separation of the cells into pseudopapillary aggregates with intervening accumulation of mucopolysaccharide rich ground substance. The expressions of Vimentin, α-ACT, α-AAT were positive, and CgA negative. Four cases were followed up for six months and norecurred. Conclusions SPT of pancreases was a kind of tumor of low potential malignancy, and the magnetic resonance and computer tomography were often to be used. The effective therapy was thoroughly resection, and the prognosis in most patients is excellent.
